Negative Achromatic Lenses are fabricated by cementing two optical elements with together, whereby the negative power element predominates. The pairing of two optical elements together corrects for on-axis spherical aberration and color. POSS’s Negative Achromatic Lenses are also AR coated on both sides, providing even brighter and sharper images. They are often utilized in applications that extend focal lengths together with positive achromatic systems or CCD lenses.
